tain new and useful improvements in Dumping-Gars, of which the following is a specification, reference being had to the accompanying drawings.

T his invention relates to new and useful improvements in dumping cars and more particularly to a dumping car which is especially' adapted for use in mines and like places, the oby'eet of the invention being to provide adumping car which can be quicklyl and readily loaded and transported from place to place and readily emptied of its contents, the body of the car being swung to the desired position before dumping.

Another obyect of the invention is to pro vide alduniping car of the above character which will possess advantages in points of eiticiency and durability, is inexpensive of manufacture and at the sainel time is simple in construction and operation.

lVith the above and other objects in view, this invention consists in the novel features of construction and the combination and arrangement of parte to be hereinafter more fully described, pointed out in the claims and shown in the accompanying drawings, in whichiigure 1 is a side elevation illustrating a number of my improved dumping cars coupled together and illust-rating in dotted lines various positions the caroccupies when in its operative position. Fig. 2 is a similar view illustrating the body of one of the cars disposed atright angles with to the truck thereof; Fig.. 3 is a longitudinal sectional View; Fig. 4; View, parts being broken away; Figi 5 is a bottom plan View; Fig. 6 is a to plan view of the platform of the car. teferring more particularly to the drawings, 1 indicates the truck of the car which is movably supported by means of the wheels 2 and secured to the upper surface ofthetruck 1 is a platform 3. Mounted upon thek plat-form and larranged centrally thereof a. circular track 4 which'is arranged around a central opening 5 formed in the platform 3 and through which pro'` jects a pivot pin 6. ltotatably mounted upc respect central is a top plan the` platform 3 .l with the ro gage With the under surface of the body 11 'l the car may be .lines in Figs. 1 an the upwardly projecting and provided with acentral opening adaplted for the reception of the upper end of t e pin 6 is a carriage 8 which is 4prefer` ably to be of the shine shape and size, as the platform 3. Rotatably mounted in the body portion of the carriage are the circularly arranged rollers 9 which are adapted to, engage with the. circular track Lt upon the rotation of thecarria-ge 8. rlhe carriage .rovided at each corner thereof lers 10 which are adapted to cnis further of the car whereby said body may be moved with respect to the carriage 8. From this it will be seen that thro-ugh the medium of the rollers 9, the carriage 8 may be readily rotated upon the platform 3 and through the medium of the rollers 107 the body 11 4of moved from |one end of the carriage 8 to the other and adapted to occupyl the' positions illustrated in dotted d 3). The body 1l of the cariis provided at one end withV a `movable gate 12 which may be quickly and readily raised to empty the contents of the car when the body of the same has been disposed to the positirh shownI by thefdotted lines in Figs. 1 and 3.

The carriage upon opposite sides thercofvwith the up wardlyprojecting ears 13 which are bifurcated itfoform the elongated open ended slots 14C which are adapted to normally receive the spaced lugs 15 formed upon opposite sides of the body 11 and arranged adjacent one end thereof. The carriage S is further provided at its end opposite the ears 13 with ears inclined recesses 17 formed in the inner" face thereof and which are adapted to receive one A of the lugs 15 when the car is moved to its operative position, as illustrated in .the dotted .lines in Figs. 1. and 3. From this it will be seen that by having the lugs 15 normally disposed within the slots 14, the body of the cai is securely held against any tiltparent from the above description taken 1n connection with the accompanying drawings that when the 'car is beingloaded the central portion of the body llwill be disposed directly above the central ,portion of the platform 3, thus throwing the entire weight of the car upon the platform.v Furthermore Ait will bc apparent that when it is desired to 8 is provided at one end 16 having the movement whatever and it will be. up?v empty the body 1l of its contents, the same will be moved longitudinally upon the roll- It will be readily understood from the' above description taken in connection with the accompanying drawings that any suitable number of cars may be coupled together and the operation of emptying one car Will not in any way affect the operation of the car next to it.

The practical operation of my improved dumping car will be readily understood with the above description taken in connection with the )accompanying drawings. lt will` also be apparent that after the car has been loaded and transported to any desired place, the saine can be quickly and readily dumped of its contents by rst rotating the carriage 8 so th'at the body 1l may be readily moved loirgitudinally 1with respect to the platform. After the'l car has been moved longitudinall/.y'so that one of the lugs l5 will engage with the ears 16, the body of the car is tilted yand the gate l2 removed so that the contents of `the car will be vquickly withdrawn therefrom.` rlhe body may then oe pushed back to its normal position and the carriage rotated until the body of the ca-ris arranged in alinement with the platform' 8. F rom this it will be seen that each car may be quickly and readily emptied of its contents and returned to its normal position without yinterfering with the car in the rear or in advance.

From this it will be seen that l have pro'- vided a` simple and durable dumping car 'which is especially adapted for use around mines and the like for conveying iron, coal and the like from the mines and thesmelters, etc., and readily emptying the same of their contents. It Will also be apparent that these grooves are extremely simple in construction and can be manufactured at a comparatively loW cost. s v

While I haveV shownand described the preferred form' of my invention, it ywill be obvious that various changes in the details invention into practice Without sacrificing departing'from the scope of the appended claims Having thus described what is claimed is l. A device of the class described including a wheeled truck having a platform, a circular track arranged centrally upon said platform, a carriage mounted upon the platform and provided with a plurality of circularly arranged rollers, adapted to run upon said track, a second set of rollers arranged at each en'd of the carriage, and a body member mounted upon the second set of rollers for sliding and tilting` movement.

2. A device of the classv` described including a wheeled truck, having a platform, a circular track mounted upon said platform, a carriage having centrally arranged rollers adapted to run upon said track, whereby the carriage may be readily rotated, `a pivot pin carried by the platform and engaging said carriage, a second set of rollers arranged at each end of the carriage, a body -member slidably mounted upon the second set of rollers, spaced ears arranged at one end of the carriage, said ears being provided with an open ended slot, spaced lugs carried by the body and lnormally arranged Within said slots, and asecond set of ears arran ed at the opposite end of the carriage and a apted for engagement with one of the lugs, upon the tilting movementof the body; i
